Application filed January 27', 1926-. Serial 84,016.

To all whom it may concern Be it known that 1;, CHARLES J. MILL R, acitizen of the United States, residing at Summit, county of Union, and,State of New Jersey, have invented new and useful Improvements in AshSeparating Shovels, of which tl'iefollowing is afull, clear, and exactspecification.

My invention relates to shovels and refers particularly to shovelsadapted for the separation of particles of different sizes.

My device is specially adaptable to the separation of ashes fromunburned coal and Clll'lhClS. i

The usually employed process for the separation of coal ashes from thelarger particles consists in placing the mixture of materials upon ascreen and then by vibration of the screen causing the fine particles tofall therethrough.-

This process requires the removal of the mixture by means of a shovel,the placement of the mixture upon a sieve, or screen, the

agitation of the latter, and the removal of.

the retained particles from the sieve. In addition to these many stepsof operation, the dust arising from the sifting step is extremelyobjectionable.

My device reduces these steps of operation and the objectionableformation of dust to a minimum and presents a means whereby theoperations can be readily and economipally performed.

In theemployment of my device, the mixture is shoveled, the ashesremoved without dust, and the final products left within the shovel forfinal disposition.

The advantages of the device of my invention will be evident upon aconsideration. of this specification and its accompanying drawings.

Figure 1 is a perspective view of one form of my device with the guardin operative position.

Figure 2 is a cross-section through the line 2-2 of Figure 1.

Figure 3 is a broken side View, showing the guard in partially raisedposition.

liigure s is a broken perspective view of the delivery end of a deviceof my invention in which the forward portion of the guard is of sieveconstruction.

The particular form of the device of my invention shown in Figures 1 to3 inclusive comprise a shovel having a non-foraminous bottom 1.0 and anupturned edge 11 around three sides. thereof, Pivotally attached at 12to opposite sides of the edge 11 is a U shaped guard having the sides13, 1st and 15. The guard isso positioned that when in its forward, oroperative, position, it will rest 'upon the angular edge 16 of the edge11, al-

lowing a space 17 between the guardelement 14: and the bottom 10 of theshovel at its forward part. A handle 18 is carried by the shovel.

In operation, the guard is thrown back on its pivots 12, 12 until itrests upon the handle 18. The device'is thenused as an ordinary shovelto remove a mixture of unburned coal, clinkers, and ashes.v The de viceis then held in a horizontal position, the guard thrown forward into theoperative position, the shovel tapped to cause the ashes to settle,andthen inclined in a. forwardly downward position allowing the ashesand small particles to escape under the guard element let through thespace 1'? into a suitablesreceptacle. When the device is returned to ahorizontal position, the coal and clinkers may be readily separated byhand.

It is to be noted that the device is simple in construction and retainsthe valuable and useful attributes of an ordinary shovel, coupled withwhich is the property of separating the ashes without the formation ofdust incident o a sieve shaking operation.

It is to be further noted that my device saves considerable time duringthe several steps of its operation, in that the materials remain in theshovel during their separation, as for instance, the clinker-s may beremoved leaving the coal in the shovel for final disposition, or thereverse operation 95 may be performed. p

The modification shown in Figure d is similar to that previouslydescribed except that the guard element 19 is of sieve construction,instead of non-foraminous as is guard element 1 L.

Other means for supporting the guard above the shovel bottom may beemployed.

I do not limit myself to the particular size, shape, number, material orarrangementv of parts as shown and described, as these are given simplyfor the purpose of clearly describing my invention.

lVhat I claim is 1. In an ash separating shovel, in combination, ashovel having a .non-foramii'ious bottom, a guard having a continuousbottom end of the shovel bottom.

3. 111 All ash separating shovel, in combination, a shovel having anon-torzuninous bottom, a hinged guard having a continuous bottom edgecapable of placement across the end of the shove], the placed guardabutting upon the shovel side forming a space between the bottom edge ofthe guard and the delivery end of the shovel bottom.

l. In an ash separating shovel, in combi nation, a shovel having anon-foraminous bottom a hinged guard having a continuous bottom edgebeing at least in part foraminous, & tora-niinous portion of which iscapable of placement across the end of the shovel forming a spacebetween the bottom edge of the guard and the delivery end of the shovelbottom.
